There has been a significant drop in support for the Queensland Government in an opinion poll published today.

A Galaxy poll in the Courier Mail newspaper shows the Liberal National Party (LNP) ahead of Labor by 10 points - 55 per cent to 45 per cent - on a two-party preferred basis.

That is not as bad for the State Government as the last poll, but Galaxy says that is because the LNP has leaked some support to the Greens.

The Greens' primary vote is at 16 per cent.

The poll is also bad for Premier Anna Bligh, showing Opposition Leader John-Paul Langbroek is ahead as preferred premier - 43 per cent to 36.

Ms Bligh's dissatisfaction rating has climbed from 64 to 69 per cent.

The poll also says 85 per cent of voters are opposed to asset sales, up from 77 per cent in February.

Treasurer Andrew Fraser says the State Government will not be distracted by the poll and remains committed to its economic policies.

"We knew that we had tough decisions to make and that those tough decisions were required and would make things tough for us politically," he said.

"Ultimately we're a government not distracted by polls and we're here to make the right decisions in the long-term interests of the Queensland economy and the Queensland community and not in our short-term political interests."

Mr Langbroek says the defection of two MPs - Aidan McLindon, the Member for Beaudesert, and Rob Messenger, the Member for Bundaberg - to run as independents, influenced the poll results where the LNP has lost support to the Greens.

"Clearly it does show that this issue of unity, people really only want to give the ball to a team that can hold it safely, carry it and get it over the try line," Mr Langbroek said.

"That's the thing that we have to show with me as the leader."

However, Greens spokeswoman in Queensland, Dr Libby Connors, says voters are disillusioned with both major parties.

"It's a great opportunity for democracy in Queensland because it could mean that - with these sorts of figures - the Greens can win seats," she said.

"We can win seats at the state level and that would finally be a serious alternative voice that both major parties would have to listen to."
